CAR-UNDERFRAME OF IRON.

, Specification of Letters Patent.

Application filed May 27, 1920. Serial N0. 384,579.

To allwiwm itmag concern:

Be it known that I, JACOB Louvre HELLEN, a subject of the King of Norway, residing at Kloften Station, Norway, have invented certain new and useful Improvements in Car-Underframes of Iron; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to car underframes of iron and has especially for its purpose to provide a connecting arrangement between the brackets or bows, which carry .the car and are supported by the wheel shafts. According to the present invention the said brackets are made of U-irons, and the free ends of the U-iron section rest directly upon the square portions of the wheel shaft. For this purpose the middle part of the iron section is bent out laterally near its ends at a right angle so as to project between the remaining lateral ribs of the iron end and the middle portions suitably welded to the inside of the ribs, thereby a rectangular claw-shaped part of the iron is formed, which grips over the square portion of the shaft.

In the drawing a constructional form of the invention is shown diagrammatically. Figure 1.is a section taken in the longitudinal plane of the wheel shaft, and Fig. 2 is a cross section on the line 11-11 of Fig. 1.

1 is the lower part of the leg of a connecting bracket arranged between the wheel shaft and the car or its underframe 10. The middle portion 2 of the U-shaped iron section is split at its lower end and is bent up to the side, as shown at 3. As seen in Fig. 2 a rectangular claw is obtained, said claw gripping over a square portion 4; of the wheel shaft 5. The square portion 4 is suitably provided at the outer end with a collar 6.

The lateral remaining ribs of the iron leg 1 are extended so as to form screw bolts 7. Upon these bolts is placed a cross piece 8, which is pressed upward by means of nuts and counter-nuts 9 upon the bolts 7, thereby the formed rectangular support is caused to fit firmly around the square portion 4.

That which I claim and desire to secure by Letters Patent of the United States is 1. In car underframes, the combination with the frame proper and the wheel shaft, of connecting brackets made of U-iron and square portions of the wheel shaft for supporting said irons, each of the latter being for that purpose split near its end and the middle portion of the U-shaped iron-section end being bent out laterally at a right angle between the remaining lateral ribs of said iron end, so as to form a rectangular clawshaped bearing gripping over the square portion of the shaft.

2. In car underframes, the combination with the frame proper and the wheel shaft, of connecting brackets made of U-iron and square portions of the wheel shaft for supporting said irons, each of the latter being for that purpose split near its end and the middle portion of the U-shaped iron-section end being bent out laterally at a right angle between the remaining lateral ribs of said iron end and welded to the inside of said ribs so as to form a rectangular claw-shaped bearing gripping firmly over the square portion of the shaft.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

JACOB LUDVIG HELLEN.
